报告人介绍:

Dr. Bipin Pandey is BBSRC Discovery Fellow at University of Nottingham. His main focus is to discover novel root adaptive responses and signals which provide greater access to nutrients and water in poor soils. Recently, Dr. Pandey discovered that ethylene acts as a key signal to sense soil compaction (Pandey et al., 2021, Science). Moreover, he co-discovered that how the hormone auxin plays a key role during low phosphate stress by promoting hair elongation (Bhosale, et al, 2018, Nature Comms; Giri et al, 2018, Nature Comms). Dr. Bipin Pandey is employing multidisciplinary approaches to uncover the mechanism of root tip elongation underpinning the root adaptive responses in poor and problematic soils.

 

直播内容:

Soil compaction represents one of the major challenges facing modern agriculture due to poor tillage practices and increasing weight of farm equipment. Mechanical impedance reduce crop yields by <75% as roots struggle to penetrate hard soils, causing billions of dollars in losses annually. Soil compaction triggers a reduction in root growth, limiting the availability of water and nutrients. Compaction also reduces the number and volume of air-filled soil pores, restricting diffusion of gases between roots and the rhizosphere. We recently discovered that plants employ the gaseous hormone ethylene released root tips to sense soil compaction. The reduced porosity of compacted soil appears to restrict diffusion of ethylene out of roots, triggering growth inhibition.

高通量植物表型平台建设注意事项

育种,是在给定的环境条件下,选择各种表型指标(产量、品质、抗性)最优的基因型材料的过程(AI育种,从这里起步)。育种工作中大约70%的工作量来自表型观察测量和筛选,是最耗人力物力的过程。

作物生理表型测量基础原理

生理表型测量的核心在于“早、快”,要在肉眼可见之前就能测量并预判出变化趋势,才是这个技术的核心价值。叶绿素荧光成像,恰好满足了这个要求。
